ADJUSTING DEVICE FOR FORMS-OF SOLE-PRESS'ING MACHINES.

SPECIFICATION forming part of Letters Patent No. 746,224, dated December8, 1903. Application filed June 23,1898. Serial No- 684,260. (No model.)A

To all whom it may concern:

Beitknown thatI, ERASTUS E. WINKLEY, a citizen of the United States,residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Adjusting Devicesfor Forms of Sole-Pressing Machines; and I do hereby declare thefollowing-to be a full, clear, and exact description of the invention,such IO as will enable others skilled in the art to which it appertainsto make and use the same.

The present invention, relates to forming and shaping machines, and moreparticularly to an improved sole-pressing machine designed to beat out,conform, and set a shoesole to the desired shape required in thefinished shoe. In these machines the shoe-sole is compressed between aniron last or form upon which the shoe is placed which acts upon theinterior surface of the bottom of the shoe and an iron form which actsupon the outer surface of the sole.

sole is of a suitableshape to conform to the contour of the bottom ofthe last or form upon which the shoe is mounted and impart to theshoe-sole the desired lateral and longitudinal curvatures. It is oftennecessary to adjust the sole-pressingform' upon its carriage so that itspressing-surface will be drawn far-- ther away from the surface of thelast or-form carrying the shoe or to more-closely approximate such lastor form, and also it is absolutely essential for the'purpose of securing5 good results that the pressing form shall be securely supported uponeach side of its longitudinal medial line in order to prevent a sidewiseor lateral displacement of the formd'ur ing the operation of pressingthe'shoe-sole.

The object of the present invention,'there-' fore, is to produce asole-pressing formwhich shall be capable of the adjustment before statedand to provide such form WlthGOlllplementarystops or abutments upon eachside of its longitudinal medial lineand provide for a simultaneous andequal adjustment of said stops or abutments, whereby the stops orabutments upon both sides of the longitudinal medial line will be of thesame height and insure the form against any lateral p This ironformwhich acts upon the outer surface of the shoegitudinal verticalsection. Fig. 3 represents a transverse vertical section through theform, taken at a point which will show the construction and operation ofthe adjustable stops or abutments. I

Similar letters of reference will be used to designate correspondingparts throughout the specification and drawings.

In the'drawings the invention is shown as applied to a form of that typeof sole-pressing machineswhich is disclosed in Letters Patent of theUnited States, issued to S. D. Tripp April8, 1884, No. 296,406,in whichthe sole i shaping action is produced by a rolling-press- 'ingmovement,the last or form which carries the shoe and the sole-pressingform being mounted upon swinging pivoted carriers, which by suitablemechanism are simultane ously rocked, so that the shoe-sole will bepressed and shaped by a rolling action which progresses along theshoe-sole in a longitudinal direction. I

In the drawings, A represents the lowerpor- 8 tion of the pivotedcarrier which supports the sole-pressing form, and B represents thepressing-form,the said pressing-form being secured to the foota of thecarrier A by'suitable setscrews b, which engage inclined notches a inthe opposite ends of the foot a, the said screws beingta-pped intothreaded bearings b in suitable upward projeclions b formedon the backof the form B. The under face of the foot a is a plain surface, and inorder to support the form B while in operation and 'against the greatpressure under which these machines are operated I have provided theform Bwith suitable stopsor abutmentsc, which, asclearly shown in thedrawings, are arranged in pairs Ioo.

Fig. 2 represents 6o at opposite ends of the form B and upon theopposite sides of the longitudinal medial line. In the illustratedembodiment of the present invention there are shown four of the stops orabutments 0; but it is obvious that any suitable number may be employed.

It is, as hereinbefore stated, absolutely essential in order to securegood results that the stops or abutments 0 upon opposite sides of thelongitudinal medial line be adjusted to project the same distance beyondthe upper or rear face of the form B, and I secure this result byconnecting each pair of the stops or abutments for a simultaneousadjustment. In the illustrated embodiment of the present invention thestops or abutments o are carried upon the upper ends of threaded studs0, which are tapped into threaded bearings 0 formedin the rear face ofthe form B, and each of the studs 0' carries a pinion 0 which may beformed integrally therewith or fixedlysecured thereto, or, if preferred,the stop or abutment c, pinion c and studs 0 may be formed integrally.For the purpose of simultaneously raising and lowering the stops orabutments in each pair I have provided a threaded stud o fitted into athreaded hearing 0 formed intermediate the bearings 0 and the stud c isprovided with a pinion c, which meshes with the pinions 0 Thescrewthread of the stud c is formed in an opposite direction to thethreads of the studs 0', as clearly shown in Fig. 3 of the drawings.

The pinion 0 may be provided with any suitable means whereby it maybeturned, and

thereby turn the pinions c and, as shown in the drawings, the pinion cfor this purpose is provided with a diametrical slot which may beengaged by the ordinary screw-driver for the purpose of turning saidpinion. The back of the form is out out or recessed at each end, asshown at 19 for the purpose of accommodating the pinions c and c.

From the foregoing description of the construction of the illustratedembodimentof the present invention it will be clear that the rotation ofthe pinion 0 will imparta simultaneous rotation to the pinions c andthat therefore if the threads of the studs 0 are of equal and uniformpitch the stops or abutments 0 will be raised or lowered simultaneouslyequal distances and that the form will be rigidly and accuratelysupported upon the foot to and a lateral tipping thereof positivelyprevented. By providing the stud c with a thread equal in pitch butopposite in direction to those on the studs 0 the gear a is caused torise and fall in unison with the gears 0 and thus to remain always infull engagement therewith. If desired, the form B may be made in twoparts, as shownthe rear part b and the removable face part 12 -411 whichevent the adjustable stops or abutments 0 will be provided in the rearpart 12 It is of course obvious and clearly within the scope of thepresent invention that instead of providing the adjustable stops orabutments c on the form B that the rear face of such form may be a plainface and the stops or abutments c secured to the foot a on the carrierAand arranged to bear against the plain face of the form B.

Having described the construction, organization, and mode of operationof the present invention, I claim as new and desire to secure by LettersPatent of the United States- 1. The combination with a form-carrier of aremovable form secured thereto, a plurality of stops or abutmentsscrew-threaded into one of said members and engaging the other, a gearsecured to each stop or abutment, an adjusting-gear engaging said gears,and a screw-threaded stem to which the adjustinggear is fixed,substantially as described.

2. The combination, with aform-carrier, of a removable form securedthereto, a plurality of stops or abutments screw-threaded into one ofsaid members and engaging the other,

a gear secured to each stop or abutment, an adjusting-gear engaging saidgears, and a stem to which the adj usting'gear is fixed, the said stembeiugscrew-threaded into one of the two first-mentioned members with athread equal in pitch but opposite in direction to those on the saidstops or abutments, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.
